S. Ducrocq et al., NEW PRIMATE FROM THE PALEOGENE OF THAILAND, AND THE BIOGEOGRAPHICAL ORIGIN OF ANTHROPOIDS, Journal of Human Evolution, 28(5), 1995, pp. 477-485
Recent field work in the Eocene Krabi Basin (south Thailand) has yield
ed a fragment of a primate lower jaw containing the second and third m
olar teeth attributed to a new genus and species, Wailekia orientale.
The specimen described here is morphologically very close to Oligopith
ecus savagei from the Fayum (Egypt), and the presence of Wailekia in t
he Upper Eocene of Thailand suggests that South East Asia may be an im
portant centre of origin for anthropoids.
